iPhone Battery Draining Too Fast
Most fast-draining iPhones are part settings, part worn battery. Tune the settings first, then check whether the battery itself is the problem.
Safety firstIf the battery is swollen (screen lifting, phone rocking on a flat table, gaps in the frame) stop using it and bring it in — swollen batteries are a fire risk.
Check your Battery Health
- Settings → Battery → Battery Health & Charging.
- Maximum Capacity under ~80% means the battery is worn and a replacement will help a lot.
- 'Peak Performance Capability' messages about unexpected shutdowns also point to a tired battery.
TipUnder 80% is Apple's own threshold for 'consider servicing.'

Stuck? Ask or talk it through
Hey 👋 I'm reading the "iPhone Battery Draining Too Fast" guide right along with you. Tell me what's happening with your device and I'll walk you through it — or what you saw after a step.
Quick start
When to bring it in
- Battery Health is under 80% or warns about service.
- It shuts off suddenly even with charge left.
- The battery looks swollen or the screen is lifting (urgent — stop using it).
- It still drains fast after you've tuned every setting.
Quick answers
- When should I replace my iPhone battery?
- Once Maximum Capacity drops under about 80%, or your phone shuts down unexpectedly, a replacement usually restores most of your day. We can read your battery health for free and quote the swap.
- How long does an iPhone battery replacement take?
- Most are same-day and often done in well under an hour at the bench. Bring it in and we'll confirm timing for your model.
